Hmmm, Microsoft was wrong to dig the windows phone so hopefully these guys come back around at some point.
I find it silly these days that we only have two options, either android or iphone.
The mobile interface was still way better than android or iphone, Microsoft should have spend more time on the development tool xamarin and allow automatically mapping any app to work in Windows phone as well.
At the moment the future for Microsoft will be Azure however they need some consumer products. Ditching hardware doesn't give the consumer a great piece of mind for any future release.
